Synthesize Multi Source Evidence

Combine independent evidence sources into one careful claim.

Builds on (2 levels back)inferred · high confidence
  • Observation vs. inference: Forensic work starts by separating what was seen from what is concluded.
  • Evidence identity: Labels, photos, and logs keep evidence tied to the right source.

Prerequisites are inferred: pending teacher review.

Re-learn the skill with worked practice and clear examples.

Combine independent evidence sources into one careful claim.

Step 1: Learn the key
A synthesis claim is strongest when [blank] evidence sources point to the same answer and contradictions are [blank].

Step 2: Use the model
Read the figure, table, control, range, or protocol before choosing an answer.
Step 3: Name the limit
Say what the evidence can support and what it cannot prove yet.
Practice

Use the synthesis figure. Which claim is strongest?

Answer: A. The claim supported by scene, lab, and history evidence

  1. Step 1: Use multiple sources: The strongest claim uses several independent sources.
  2. Step 2: Avoid ignoring data: Ignoring a source weakens synthesis.

Why it's right: A multi-source claim is stronger than a one-clue claim.

Why the others miss:
  • B: One clue is weaker.
  • C: Ignoring lab evidence is not synthesis.
  • D: Length is not evidence.

Guided notes

Fill these in as you work through the lesson.

Big idea: Combine independent evidence sources into one careful claim.
Key terms: write the meaning
  • Evidence source (place the data came from):  
  • Converging evidence (different clues pointing same way):  
  • Contradiction (evidence that does not fit):  
  • Synthesis (combining parts into a whole):  
The rule

A synthesis claim is strongest when   evidence sources point to the same answer and contradictions are  .

Check yourself
  1. Which sources agree? 
  2. Which source conflicts? 
  3. What claim fits the most evidence? 
Work one example

Given a photo log, biomolecule test, and witness statement, write the one claim they support and one limit.
